The carrying casetopis provided with a record holding spring 5,, which bears againstthe records stored on the turntable shaft,

and performs thefunction also'of securing the oscillator in the lid for carrying. purposes. It is secured to said top. 6 is the carrying case handle, secured by any suitable means such as carrying handle screws 7, screwed into the motor board through openings in carrying case bottom, 1.. 8 are the carrying case feet, preferably of some resilient material such as rubber, securedby a hollow rivet 9 provided with a large head, and secured to carrying case bottom 1. 10 is the motor board holding pin, see Figure 14. 11 is the motor board, which is provided with a flange 12, on all four sides, the flange 1n the rear being pierced to receive a holding pin 10, and in the front being provided to receive carrying case handle screws 7. This board is the foundation upon which are secured various partsof the phonograph,

and forms, with the various parts of the phonograph a complete phonograph unit to be placed in the case. as described or any other type or finish of case, as I have found that wooden cases are admirably suited for the purpose where leather covering or decorative work is desired. 13 is the turntable,

which is mounted on turntable shaft 14, by 5 means of a tapered fit or other suitable mounting. The turntable is provided with the usual felt on the top surface, and a hub inv the center for mounting purposes." 15 is the top motor plate, secured to raised lugs from the motor board 52, bybolts 16. 17 is the bottom motor plate spaced from the top motor plate 15 by means of spacing members 18, through which bolts 16 operate, thus securing the two motor plates in rigid con-' struction, and which are in turn rigidly.

secured to the motor board. Turntable shaft 14 is mounted through the top motor plate a bearing, and is supported and operates in a bearing secured in the bottomimotor plate. I This shaft 14 I have found advisable tomake spherical on the bottom for practical reasons. Turntable shaft 14 is provided with teeth to form a pinion 31, these as shown are integral with shaft 14. 19 is 6-3 the main spring. 20 is the spring barrel shaft, which shaft is mounted to'revolve in top and bottom motor plates, 15 and 17 respectively. 21 is an enlarged head stud over which is secured main spring 19 by means of a pear-shaped opening 22. Spring barrel shaft 20 is driven by winding gear 23 in winding, and is secured to the same by a flattened shaft connection as shown in Figures 10 and 11. The outer end of the mainspring issecured to the spring is an intermediate gear driving winding gear- 23 and isdriven by pinion 33. Gear 32is mounted to operate on intermediate jgear shaft 49 which shaft is stationary and secured rigidly to the motor board.

35 is the winding sleeve, flanged at its up per end to form a top bearing on the motor board, the motor board being pierced and flanged down to form a top bearingQfor the sleeve. The bottom end of the sleeve is solid v and formed to mount pinion 33 thereon and formed to a bearing to operate in bot-tom motor plate 17 and provided with a threaded portion and nut secured thereon to prevent the withdrawal of the same. In this sleeve 35 is a pin 36 over which straddleswinding' crank 37 for winding purposes. 38 1s a wind check spring, one endof which is secured to motor board and the other end of which is unsecured but wound tight around said sleeve 35. On turntable shaft'14 is secured spiral driving gear v39 whichdrives the governor spiral or worm-40, which worm is secured to or formed integral with governor shaft 41, which shaft is mounted at its ends in bearings'secured to the top motor plate. 42 are governor weights, mounted on governor springs 43,'one end of which sprlngs are secured to collar 44 secured to the governor shaft 41, the other end of said springs being secured to sliding: collar; 46 being the brake to operate on said collar'to regulate speed and being [adjustable by means of speed control lever 47, operated by screw 48. v V

While I claim nothing in this application concerning the reproduction mechanism,

such as the oscillator and the reproducer head, the same being the subject matter of other applications, I will simply briefly enumerate some of the parts. 7 r

50 is the oscillator, as shown a truncated cone of flexible material carried by reproducer head 51 and detachable therefrom, and in the instrument described is folded threefold and placed in the cover under spring 5, when not in use. It is broken off as shown in Fig. 1 and folded as shown in Figs. 5 and 6 and is not further described or illustrated, as the same is the subject matter of Patent No. 1,703,664, to be issued Feb. 26, 1929.

eproducer head 51 is carried on swinging arm 52 and swings across the record; concerning this I claim nothing herein, as the same is fully covered in co-pending applications. The oscillator above referred to is a device which I term an oscillator for setting up air vibrations by being oscillated by the reproducer needle.

For general information concerning the operation of this phonograph described, oscillator 50 is carried by bell-crank fulcrumed on reproducer head 51, said bellcrank carrying said oscillator at one end and a needle operating in the record at the other end. This, also, is fully described in co-pending applications, and nothing is claimed herein concerning the same.

I have not attempted to describe other detailsof the phonograph, such as the needle box, storage box, governing and relief controls, other than what is necessary to understand the invention.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. In a phonograph provided with a turntable operated by gears operating in a plane parallel with the plane of operation of said turntable, a spring driving said gears and a winding mechanism for winding said spring operated by gears operating in a plane parallel to said plane of operation of said turntable, and a crank for turning one of said gears operating above the plane of operation of said turntable.

2. In a phonograph provided with a turntable and means for operating the same, mechanical means for energizing said operating means, operative by a shaft parallel with the turntable shaft, and a crank for operating said shaft operating above the plane of operation of said turn-table.

3. In a phonograph having a turntable and a spring motor, means for winding said spring motor consisting of a sleeve rotatively operative parallel to the axis of the spring of said motor, forming a shaft, which shaft by means of gearing winds said motor and means for turning said sleeve from above the plane of rotation of said turn-table consisting of a winding-key entering said sleeve and extending above said turn-table and means for preventing said key from revolving in said sleeve.
